The former The Amazing Race and Big Brother couple wed atop the AT&T Center, a 32-story high-rise in downtown Los Angeles, on Saturday in a ceremony that will air during the finale of WE tv's My Fair Wedding reality show's current season on Saturday, December 15 at 9PM ET/PT, Peoplereported.
Reilly arrived at the wedding at sunset via helicopter because "she wanted to arrive like a big celebrity," David Tutera, celebrity wedding planner and host of My Fair Wedding, told People.
"The guests will watch her arrive on live camera before she walks down the aisle, which to me is one of the most over the top processionals ever."
The bride wore an ensemble that was "not at all a bridal gown," according to Tutera, as Reilly reportedly walked down the aisle in a floor-length, silver-sequined Missoni dress which featured a sweetheart neckline.
"She's more comfortable in evening wear that you would wear down a red carpet than a white carpet," he said, adding that former ninth-season Big Brother houseguest Chelsia Hart served as one of Reilly's bridesmaids while twelfth-season houseguest Matt Hoffman officiated the ceremony.
Hart wore a gold and silver-sequined cocktail dress and Villegas sported a white dinner jacket with black tuxedo pants. Reilly and her groom exchanged vows in front of 130 guests, which included Big Brother couple Jeff Schroeder and Jordan Lloyd, and then enjoyed a silver and white-themed reception that reportedly "looked like the patterns of glittering stars."
"She wanted to have something that made her feel like she was in the sky," Tutera told People of the venue. "I wanted one of the highest locations in Los Angeles, giving her the ability to be the closest to the stars."
Reilly and Villegas first met when they competed on Big Brother's twelfth season in 2010. After beginning a "showmance" during the competition, the pair continued dating and got engaged on Valentine's Day before returning to Big Brother in 2011 as part of last summer's thirteenth season "duos" twist in which three pairs of former houseguests were given a second chance to compete on the show.
While Villegas was evicted -- twice -- from the Big Brother house midway through the competition, Reilly made it to the thirteenth-season finale, where she took home the show's $500,000 grand prize after winning a 4-3 jury vote over fellow contestant Porsche Briggs.
The couple then made their third appearance on a CBS reality series within the last two years when they competed on The Amazing Race's twentieth edition, which premiered in February. They finished the season's final leg in third place.
